My mother (aged 70+) has received a letter from her local police containing an accusation of dangerous or careless driving at 7:15 on Saturday May 16th. Beyond that there is no other detail and apparently the police won't expand on it until my mother completes a form. This has two sections: one that describes the incident and has a tick box that asks her to confirm that she was driving the vehicle bearing reg XXXX PZR (her reg no), and a second section that states that she wasn't driving but that she is the registered keeper of vehicle XXXX RDZ (a different reg no). She is adamant that she was at home at the time this offence is supposed to have occurred, but there are no independent witnesses. At a push she could request the CCTV footage from the nearby motorway junction that would show her arriving home at around 5:30 and not leaving again that evening. Chucking the form in the bin isn't an option - she'll more than likely be fined more than she would be if she admitted to an offence she didn't commit, for non-compliance with procedure. Is the best advice to march into the station and ask them to sort it out, or is there some sort of scam going on that's passed us by?
